SAD-IRON HEATER.

Specification of Letters Patent No. 35,139, dated May 6, 1862.

To all whom it may concern:

Be it known that I, GARDNER OHILsoN, a citizen of the United States ofAmerica, and a residentof Boston, in the county of Suffolk and State ofhlassachusetts, have invented an Improved SadIron Heater, and do herebydeclare the same to be fully de scribed in the following specificationand represented in the accompanying drawings, of which Figure 1, is atop view; Fig. 2, a side elevation; Fig. 3, a vertical section, and Fig.4, an underside view of such heater.

It is intended to be used on a stove, and when so employed it is to restin one of its holes designed for the reception of a boiling vessel.

The stand A, of this heater is a hollow pyramidal frustum, having itsbase plate B, furnished with a projecting flanch or shelf O, and anannular extension D, the latter being arranged so as to project belowsuch base, as shown in the drawings. The said pyramidal stand issurmounted by a hollow cap guard or heat retainer D, which is alsofrusto pyramidal in form, except that each side or plate of it isnotched or recessed as shown at a. Above the guard is a handle IE, itbeing suitably fastened there to and to the stand A, or either.

From the middle of the inner surface of each of the side plates, 5, b,I), of the stand A, a projection or heat conductor G, is extendeddownward and so as to go below the base plate B, and reach into the fuelof the fireplace or the flame thereof when the sad iron heater isinserted in the boiler opening of a stove and in such manner as to bedirectly over the fireplace thereof, or in such close proximity theretothat the flame or heat from the fuel when in combustion may come incontact with such part G, and impart heat to it. The heat will beconducted into the side or face plate of the stand A, and when sad-ironsare placed on the shelf or ledge C, and with their smoothing faces incontact with the outer surfaces of the pyramidal stand A, such ironswill be heated.

Each face plate 5, of the heater is thicker in its middle than it is atits edges or junctures with the two next adjacent plates and graduallydecreases in its thickness from such middle to such edges or junctures,the same being as shown in Fig. 5, which is a horizontal section of thestand. The object of thus making each face plate is to cause the wholesmoothing surface of a sad-iron when placed against the outer face ofsuch plate to be uniformly and evenly heated.

The heat conductors may be made tapering in shape, as shown in thedrawings, or they may have any other desirable and proper form.

WVhen sad-irons are arranged on the ledge O, their toes or smaller endswill project underneath the cap or guard, which will not only keep theirons from being accidentally thrown off the heater, but will serve toarrest the heat escaping upward from them and the sides of the stand A,and either retain it in contact with the irons, or radiate it more orless upon them.

By means of the heat conductors arranged within the hollow stand A asdescribed, the heating of the stand, when upon a stove will be greatlyfacilitated.

My invention when made as above described or under a proper change inits form may be used for heating tailors or other kinds of smoothingirons or various other articles.

I lay no claim to anything described or represented in either of theUnited States Patents numbered 5971 or 7159, as in neither of them isthere found any device which is the same or the equivalent of the guardD, as constructed and arranged with the pyramidal stand A, in the mannerI have shown and represented, for my pyramidal guard is so arranged andmade that the toe part of each sad iron can be passed upward under theguard and so that the heel may rest on the fianch O. The guard not onlyserves the purpose ofa heat retainer but opcrates to prevent the sadiron from being accidentally thrown off the flanch C.

Therefore, I claim- 1. The arrangement of the guard or heat retainer D,constructed substantially as described, with the pyramidal stand A, andthe shelf or fianch O, thereof.

2. I also claim the hollow pyramidal stand A, with its sides or platesprovided with a series of heating conductors G, G,

arranged With respect to them and so as to extend down through theopening D, or base of such stand substantially in the manner and for thepurpose as set forth.

5 3. I also claim a sad iron heater composed of the hollow pyramidalstand A, (or the same and the guard 1),) and the heat conductors andhaving the plates of the stand constructed substantially as describedand for the purposes as set forth. GARDNER CHILSON. Witnesses:
